"(Trump) should not be underestimated," Avenatti said when asked about his 2020 plans on MSNBC. "And if the Democratic Party makes the same mistake that others have made, namely running 15 experienced candidates — politicians — against him, we should not be surprised when the outcome is the same as 2016."

Avenatti added that he thinks the only kind of person who can beat Trump is "a street fighter" who "better have some charisma, and better be ready for a very brutal campaign."

Of course, Avenatti is a draw for Democrats even if he is not seriously considering a White House bid, thanks to his work for Daniels and his constant presence on cable news. Trump's former personal attorney, Michael Cohen, paid Daniels $130,000 days before the 2016 presidential election to keep quiet about a one-night sexual affair she alleges she had with Trump more than a decade ago. Trump has denied the encounter.

Iowa Democrats have had difficulty booking events that typically attract top-tier presidential hopefuls, since few of them are willing to tip their hands this early by visiting Iowa, which holds the nation's first presidential nominating contest.

I look forward to speaking at the Iowa State Democratic Wing Ding next month. Extremely honored to be included as one of the speakers. It promises to be a great event as always! #Basta#FightClub
